Nanostructured diamond capsules maintain high-pressure samples for materials analysis

Preserving high-pressure states of novel materials at ambient conditions is a long-sought-after goal for fundamental research and practical applications. A recent joint project by researchers in China and the United States showed that properties of high-pressure materials can be maintained in free-standing, nanostructured diamond capsules without the support of traditional bulky pressure vessels.

Next-gen spacecraft: In-development solid oxide fuel cells offer bipropellant enabled electrical power supply

Mass and volume limitations make it challenging to load a spacecraft with all the equipment needed for a mission. An effort led by the Air Force Research Laboratory is developing a solid oxide fuel cell that converts chemical energy in a spacecraft’s bipropellant into electricity, thereby allowing an existing spacecraft component to be used as an auxiliary power supply.

Video: Approval of industrial seafloor mining trial elicits scrutiny from marine scientists and journalists

On Sept. 7, 2022, Canadian mining startup The Metals Company announced the International Seabed Authority greenlit their plan to conduct an industrial seafloor mining trial to extract polymetallic nodules. While marine scientists are concerned about the environmental effects of deep-sea mining in general, an investigative report by The New York Times questions the choice of The Metals Company to conduct this trial.
